Hope you are doing well.
it would be very helpful if the products could be sorted either by
date, alphabetically or random.
Right now they are sorted by entry date as far as i can tell. This does not work too well for products that are typically sorted alphabetically.
it would be great if those options could be added to the product settings.
Hard coding the plugins directory path in ecommerce-product-catalog.php only works for standard WP implementations. If wp-content is not in the same directory as the standard WP code then the plugin does not work anymore.
This is a standard setup if WP is source controlled e.g. via Git
Although you can change the Categories Parent URL in the settings, so categories appear as /my-custom-slug/category-name/, products seem to be hardcoded to be /products/product-name.
Would it be possible to add a field to allow you to customise the Parent URL for products?
If you are using the classic list, then the product short description is added besides the picture.
However, if shortcodes are used in the product short description, then they are not removed from the text (only html tags).
I would suggest removing shortcodes the WP strip_shortcodes function in the content-functions.php file.
I confirmed that some lang file was added.
But WordPress locale for Japanese is just "ja" not "ja_JA".
You can see the list of all langages. http://wpcentral.io/internationalization/
So I think you should rename the file to "al-ecommerce-product-catalog-ja.mo".
